6.Advertisement: For sinus pain, three out of four hospitals give their patients Novex. So when you want the most effective painkiller for sinus pain, Novex is the one to choose.
Which of the following, if true, most seriously undermines the advertisement’s argument?
(A) Some competing brands of painkillers are intended to reduce other kinds of pain in addition to sinus pain.
(B) Many hospitals that do not usually use Novex will do so for those patients who cannot tolerate the drug the hospitals usually use.
(C) Many drug manufacturers increase sales of their products to hospitals by selling these products to the hospitals at the lowest price the manufacturers can afford.
(D) Unlike some competing brands of painkillers, Novex is available from pharmacies without a doctor’s prescription.
(E) In clinical trials Novex has been found more effective than competing brands of painkillers that have been on the market longer than Novex.
the answer is D.
我選B 我看不出D哪裡可以weaken 我覺得B有針對為何醫院用Novex原因做解釋
如B所說可推出這種藥效用便不是醫院是用他的原因 應此weaken conclusion
所以想請教大家 的意見
謝謝
